Abstract

Non-linear optical properties of titanium nitride nanoparticles were examined using the modified z-scan technique with simultaneous acquisition of the Rayleigh scattering at the direct angle to the polarization plane of a probe laser beam. The real and imaginary parts of the effective dielectric function of nanoparticles, depending on the pump intensity, at the wavelength of 355 nm and the laser pulse energy of 5.8 mJ were reconstructed from the obtained experimental data and displayed using the Cole-Cole diagram technique.
